MYB — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0025510, designated HvMYB, encodes a protein with SANT/Myb and homeodomain-like domains, and is annotated with DNA binding transcription factor activity, RNA polymerase binding, metallopeptidase activity, and transcriptional co-regulator activity. It is associated with circadian rhythm regulation, including upregulation and entrainment of the circadian clock and circadian regulation of gene expression. The gene is linked to starch metabolism, proanthocyanidin anabolism, pigmentation, and secondary growth. It has been connected to grain yield, grain weight, grain length, seed weight, and grain size, as well as photosynthetic rate, chlorophyll content, and stomatal resistance. Associations also include fungal disease response, drought tolerance, temperature stress response, and thermotolerance. The protein localises to the nucleus and is linked to regulation of endosperm development, autophagy, and the MAPK cascade.
